There's a few differences: 1. You have to hunt down a check or track down your account number and routing number from your bank where you have your debit card in your wallet. 2. We've found that customers are more skittish to share their bank account than their debit card number. I can try to guess why, but that's at least what we see. 3. Bank account numbers can't be verified in real-time (takes 2-3 business days) where debit card numbers can. This can lead to big issues the first time a customer gets paid and a poor initial experience.
